+# ==== Purpose ====
+#
+# Provide a earier way to restart SQL thread when you want to stop sql thread
+# and then start it immediately.
+#
+# Sources stop_slave_sql.inc to stop SQL thread on the current connection.
+# Then issues START SLAVE SQL_THREAD and then waits until
+# the SQL threads have started, or until a timeout is reached.
+#
+# Please use this instead of 'STOP|START SLAVE SQL_THREAD', to reduce the risk of
+# test case bugs.
+#
+#
+# ==== Usage ====
+#
+# [--let $slave_timeout= NUMBER]
+# [--let $rpl_debug= 1]
+# --source include/restart_slave_sql.inc
+#
+# Parameters:
+#   $slave_timeout
+#     See include/wait_for_slave_param.inc
+#
+#   $rpl_debug
+#     See include/rpl_init.inc
